## Conversion formula

The conversion factor from feet per second to knots is 0.59248380129641, which means that 1 foot per second is equal to 0.59248380129641 knots:

1 ft/s = 0.59248380129641 kt

To convert 388.4 feet per second into knots we have to multiply 388.4 by the conversion factor in order to get the velocity amount from feet per second to knots. We can also form a simple proportion to calculate the result:

1 ft/s → 0.59248380129641 kt

388.4 ft/s → V(kt)

Solve the above proportion to obtain the velocity V in knots:

V(kt) = 388.4 ft/s × 0.59248380129641 kt

V(kt) = 230.12070842352 kt

The final result is:

388.4 ft/s → 230.12070842352 kt

We conclude that 388.4 feet per second is equivalent to 230.12070842352 knots:

388.4 feet per second = 230.12070842352 knots
